Measuring Audio and Visual Speech Synchrony: Methods
نویسندگان
چکیده
Speech is a means of communication that is intrinsically bimodal: the audio signal originates from the dynamics of the articulators. This paper reviews recent works in the field of audiovisual speech and more specifically on techniques developed to measure the level of correspondence between audio and visual speech. It overviews the most common audio and visual speech front-end processing, transformations performed on audio, visual or joint audiovisual feature spaces and the actual measure of correspondence between audio and visual speech. Finally, applications of this specific task are

Measuring Audio and Visual Speech Synchrony: Methods and Applications
Speech is a means of communication that is intrinsically bimodal: the audio signal originates from the dynamics of the articulators.

متن کاملAn audio-visual approach to measuring discourse synchrony in multimodal conversation data
This paper describes recent work on the automatic extraction of visual and audio parameters relating to the detection of synchrony in discourse, and to the modelling of active listening for advanced speech technology. It reports findings based on image processing that reliably identify the strong entrainment between members of a group conversation, and describes techniques for the extraction an...
متن کاملDetection of auditory (cross-spectral) and auditory-visual (cross-modal) synchrony
Detection thresholds for temporal synchrony in auditory and auditory-visual sentence materials were obtained on normal-hearing subjects. For auditory conditions, thresholds were determined using an adaptive-tracking procedure to control the degree of temporal asynchrony of a narrow audio band of speech, both positive and negative in separate tracks, relative to three other narrow audio bands of...
متن کاملRobust audio-visual speech synchrony detection by generalized bimodal linear prediction
We study the problem of detecting audio-visual synchrony in video segments containing a speaker in frontal head pose. The problem holds a number of important applications, for example speech source localization, speech activity detection, speaker diarization, speech source separation, and biometric spoofing detection. In particular, we build on earlier work, extending our previously proposed ti...
متن کاملCross-Modal Matching of Audio-Visual German and French Fluent Speech in Infancy
The present study examined when and how the ability to cross-modally match audio-visual fluent speech develops in 4.5-, 6- and 12-month-old German-learning infants. In Experiment 1, 4.5- and 6-month-old infants' audio-visual matching ability of native (German) and non-native (French) fluent speech was assessed by presenting auditory and visual speech information sequentially, that is, in the ab...
